That really depends on your deployment - how sensitive would you be to 
someone having their credentials sniffed off the wire? How likely is it 
that someone will attempt a non-encrypted bind? YMMV.

By the time the bind code is evaluating whether a secure transport was 
used the credentials have already passed over the wire. If you are 
sensitive to this, then I would suggest you disable the non-secure port 
by setting its port # to zero, then the only way to attempt a bind is 
over the secure port using SSL.
